oai:localhost:PNK-90662023-09-18T04:17:44Z Infrared spectroscopy reveals the reactivity of fatty acids on copper surfaces and its implications for cultural heritage objects Boyatzis, Stamatis C. Fragkos-Livanios, Leonidas Infrared spectroscopy Cc-BY The reactivities of various fatty monoacids and diacids on copper metal-containing surfaces were investigated through reflection–absorption infrared spectroscopy. The formation of copper carboxylates is detected on pure copper surfaces, while copper and zinc carboxylates are simultaneously formed on brass surfaces. Following the decrease of acid carbonyl and the formation of carboxylate infrared bands, it is shown that fatty monoacids C8 and C10 react with clean/polished copper and its zinc alloy within 2–4 h, while those with chains > C12 react within days. At the end of the processes, only the corresponding metal carboxylates are detected in all cases. An explanation for the above is offered on a molecular mobility and acidity basis, where the lower monoacids (liquids in room temperature), also having lower pKa values, favor higher reaction rates. Furthermore, it is argued that longer-chain fatty monoacids, when deposited from their solutions, allow for favorable orientation resulting in self-assembled monolayer-type molecular packing on the copper surface, which may additionally rationalize the slower reaction. 2023-09-18T04:17:43Z 2023-09-18T04:17:43Z 2023 Book Book chapter https://link.springer.com/article/10.1186/s40494-023-01023-1 https://dlib.phenikaa-uni.edu.vn/handle/PNK/9066 en application/pdf Springer |
